蠕動(dòng)泵是恒流泵和軟管泵的統(tǒng)稱,其機(jī)械原理十分簡(jiǎn)單,是通過對(duì)泵管進(jìn)行交替擠壓和釋放使管內(nèi)形成負(fù)壓來傳送流體的。
Tip1:choosetherightpumptube
Whenselectingtheperistalticpump,considerwhetherthedeliveredliquidwillcorrodethepumppipe,becausethereisnopumppipethatcanwithstandallliquids.First,determinewhethertheliquidisstrongacidorweakalkali.Refertothecorrespondingchemicalsolubilitytableforcomparison,ordoimmersiontesttoensurethatthepumppipecanbeused
技巧1:選擇適合的泵管
在選擇蠕動(dòng)泵的時(shí)候要考慮輸送的液體會(huì)不會(huì)腐蝕泵管,因?yàn)闆]有任何一種泵管可以耐受所有液體的,首先要確定液體的性質(zhì)是強(qiáng)酸還是弱堿,參考對(duì)應(yīng)的化學(xué)相溶表對(duì)比使用,或者做浸泡實(shí)驗(yàn),確保泵管可以使用
Tip2:extendservicelife
Whentheperistalticpumpisnotinuse,looseningthepressureblockcanprolongtheservicelifeofthepumppipe.Theperistalticpumpisdeliveredbythesuctionandfluidgeneratedbythenaturalreboundofthecompressionhoseandthehose.Therefore,aslongasthepumppipeisinthenaturalstatewithoutpressure,theservicelifeshouldbeprolonged
技巧2:延長(zhǎng)使用壽命
蠕動(dòng)泵在不用的狀態(tài)下松開壓塊可以延長(zhǎng)泵管的使用壽命奧,蠕動(dòng)泵是靠壓縮軟管和軟管自然回彈產(chǎn)生吸力和流體輸送的,所以只要泵管處于自然狀態(tài)不受壓,使用壽命理所應(yīng)當(dāng)延長(zhǎng)的奧
Tip3:dailyinspection
Theperistalticpumpwillcauseirreversiblewearofthepumppipeintheprocessofuse.Theperistalticpipeitselfisalsoavulnerablepart.Onceitisdamaged,itwillcauseleakage.Therefore,beforedailyuse,itisnecessarytopayattentiontotheplacewhereitiseasytowear,whichisalsoamethodtopreventthedamageofthepumppipefromcausingleakage
技巧3:日常檢查
蠕動(dòng)泵在使用過程中會(huì)造成不可逆的泵管磨損,本身蠕動(dòng)管也是易損件,一但破損就造成泄露,所以在日常使用前就要注意檢查容易磨損的地方,也是防止泵管破損產(chǎn)生泄露的方法

技巧4:控制轉(zhuǎn)速
前期選型的時(shí)候要滿足流量的前提下,可以盡量控制泵頭速度在300轉(zhuǎn)以內(nèi),因?yàn)檗D(zhuǎn)動(dòng)越快,相應(yīng)的泵管的使用時(shí)間就會(huì)避免不了的縮短,所以在選擇的時(shí)候盡量選擇泵管更大一點(diǎn)的管徑,這樣就可以在不影響流量的時(shí)候降低轉(zhuǎn)速

技巧5:定時(shí)清理雜物
蠕動(dòng)泵是一款高精度的儀器,所以任何一點(diǎn)點(diǎn)泵殼和泵管上的雜物很容易影響精度的,那怕是微小的變化也會(huì)造成泵管的過度過早磨損,嚴(yán)重的會(huì)影響到泵頭造成泵頭的損壞。所以在在使用過程中要注意清理泵殼和泵管上的雜物的,并定時(shí)清理

技巧6:蠕動(dòng)泵選型
在選型的時(shí)候一定要注意理論流量一定要大于實(shí)際流量才行,蠕動(dòng)泵管較軟,因此其所產(chǎn)生的負(fù)壓和排出壓力較小,如果輸送的液體有一定粘度或者管路有一定的長(zhǎng)度,就會(huì)造成實(shí)際流量的損失,為了達(dá)到需要的流量選型時(shí)理論流量就要稍高于實(shí)際流量。

技巧7:蠕動(dòng)泵管入口越短越好
管路的接頭和口徑不要低于泵頭所裝卡管的口徑,蠕動(dòng)泵吸力是由泵管回彈產(chǎn)生的,如果管路特別是入口管路過長(zhǎng)或者口徑變小,就會(huì)造成吸入端阻力過大,阻力過大泵管回彈就會(huì)受阻,因此輸送的實(shí)際流量會(huì)受到極大的損失

技巧8:泵頭上用蠕動(dòng)泵專用管,其余連接管可用普通的管道。蠕動(dòng)泵上用的擠壓管由于需要良好的抗壓回彈性,抗撕性能,因此這些泵管的材料純度比較高,幾何尺寸精度較高,這就會(huì)造成蠕動(dòng)泵管價(jià)格較高。因此采用普通管做連接管會(huì)比較經(jīng)濟(jì)。
